Knowledge of patients’ social settings can help the den-tist understand patients’ expectations and the evolution oftheir dental status. Family and social circle norms influencepeople. There are still sectors of society that are not dis-tressed by tooth loss or by the prospect of wearing com-plete dentures. Other patients come from unfortunate cir-cumstances where care has been inadequate, but given theresources, they would have done better. Most people haveclose friends or relatives whose judgment they value. It ishelpful to have patients identify these people during the ex-amination and, if possible, gain some insight into their view.[1] However, it is the primary role of the dental clinicianto suggest an optimal prosthetic treatment for the patient.Nevertheless, techniques and methods of prosthetic treat-ment lower in cost are still largely favoured by patients aswell as dental clinicians. Yet, dental prostheses must meetcertain parameters for functional life expectancy. [2, 3, 4]PURPOSE:To analyze common errors performed by  dental cli-nicians that could result in adverse effects on the patient’smasticatory system.MATERIALS AND METHODS:The analysis is focused on prostheses built in privatedental practices in Varna city and Varna area. 38 ( male-12, female- 26) patients who were referred to the Departmentof  Prosthetic Dental Medicine and Orthodontics, Facultyof Dental Medicine –Varna, have been examined. The ob-jectively collected data from extra and intraoral examina-tions and paraclinical tests has been documented in photo-graphs. A package of application software for analysis ofepidemiological and clinical researches - SPSS for Windowsversion 16.00 (15.11.2007) was used. The following meth-ods of statistical analysis (descriptive statistics) were appliedto our study: frequency analysis and cross tabulation for cat-egorical data.RESULTS:In 100% of cases under study the tendency observedis towards neglect of the preventive, functional and estheticrequirements for the permanent prosthetic restorations withvarying degrees of consequences. The types of prostheticrestorations are various-fixed prostheses (anterior cast res-torations with esthetic ceramic/ resin veneers) and remov-able prostheses (acrylic dentures fabricated by conventionalcuvette technique- partial dentures with wrought wire claspsand complete dentures).The data shows the following consequences of ne-glecting general prosthetic principles:1. Biologic parameters:Figure 1. - Occlusal disharmonies 76.32 % ( 29 outof 38 patients)Figure 2. - Complete destruction of abutment teeth(fixed partial restorations- 66.66%- 16 out of 24 restora-tions; removable partial dentures- 89.47% - 17 out of 19 re-movable partial dentures)Figure 3. - Complex damage of periodontal structuresdue to deficient crowns  62.50% -15 out of 24 fixed pros-thetic restorationsFigure 4. - Complex damage of supporting tissues-mucosa, residual ridges    88.37% -38 out of 43 removablepartial dentures2. Functional parameters:Inefficient mastication total 89.47% -  34 out of 38patients ( 87.50% - 21 out of 24 fixed prosthetic restora-tions and  88.43% - 38 out of 43 removable partial and com-plete dentures).Temporomandibular disorders 55.26% ( 21 out of 38patients).Phonetic problems.Over-extension of denture borders - 76.74% of re-movable partial and complete dentures ( 33 out of 43 re-movable dentures).http://dx.doi.org/10.5272/jimab.2014201.510/ J of IMAB. 2014, vol. 20, issue 1/ http://www.journal-imab-bg.org 5113. Esthetic parameters:Figure 5. - Lack of soft tissue esthetics.Figure 6. - Influence of  vertical occlusal discrepancyon facial appearance.Figure 7. - Neglecting the smile line.Inappropriate position and contour of anterior fixedrestoration/ Inappropriate selection of artificial teeth.Obvious neglecting of smile design due to patients’socio-economic status.DISCUSSION:When the restoration of missing teeth involves com-plete rehabilitation of the oral cavity (functional and aes-thetic) it is termed as full mouth rehabilitation. We knowthat full mouth rehabilitation is a combination of multipleprocedures done to restore the oral cavity to its original con-dition.[5] The successful outcome of prosthetic treatmentdepends upon the combined efforts of three people:- The clinician - who makes a diagnosis, prepares atreatment plan and undertakes the clinical work.- The dental technician - who constructs the variousitems, which culminate in the finished dentures.- The patient - who is faced with coming to termswith the loss of all the natural teeth, having to adapt to thedentures and accepting and accommodating their limita-tions.[6] Modern dentistry offers various methods and tech-niques for restoring the masticatory abilities of patients. [1,5, 4, 6, 7 ] Therefore, any clinical decision resulting in dam-aging the masticatory system of the patient is regarded astotally unacceptable. Although the patient clearly has the fi-nal word on the appearance of the dentures, there are somesituations in which clinical judgement is particularly impor-tant. [6]CONCLUSION:The prosthetist’s role is crucial for the final result ofthe prosthetic treatment. The dental clinician should be theone who sets the limits for reasonable compromises whenconsidering the laboratory and/or financial implications forthe patient. Dental clinician’s competence is called intoquestion whenever inappropriate and substandard materialsand technologies are still applied.Fig. 1. Occlusal disharmoniesFig. 2.
